Fixed abrasive diamond wire saw is widely used for slicing crystal quartz to
manufacture new piezoelectric dynamometers. However, the process has always the problem
of slicing out-of-straight influencing the dynamometer.s indicators, the optimization methods
of machining and slicing process are studied in the paper. Developments of fixed abrasive
diamond wire machining are reviewed firstly. A research system is built to monitor process
and measure cutting forces. The 3-axis forces and their relationship with tension-force are
investigated by measured curve. Force analysis of diamond wire at changing direction is
shown in the experiment and the rule of slicing straight is found. Finally, suggestions on
slicing parameters and methods are put forward.
